Captcha, but not for bots, for humans.

Perhaps a simple logic puzzle wrapped inside a question about programming? That would require both factual knowledge of programming and at least a modicum of thinking ability.

That's your captcha for posts and voting permissions.

The problem I see is how to generate the captcha question/reply pairs. Perhaps something wiki style?



For each problem in Project Euler there is a forum that is open only after you solve it. One of the hard ones has "First!" comment in there.
